The general object of this invention is to provide a novel street markerfor use with a series of similar markers to be anchored in the pavementto provide stop lines for vehicles and to define a safety zone or walkfor pedestrains at street intersections.

The leading characteristic or my improved marker is the fact that it iscast from rust-proof metal capable of being burnished to have impartedthereto'a permanent polished surface.

Other features of the invention relate to a novel construction of parts,and use of novel means associated therewith for penetrating the pavementand anchoring the marker therein.

The invention is illustrated in the accompanying drawing in which:

Fig. l is a bottom plan view of the marker;

Fig. 2 is a View in side elevation thereof, one arm of the anchoringmember being shown in dotted lines before being bent to its penetratingposition; I V

Fig. 3 is a sectional view showing the markerin anchored position on asection of pavement; and

Fig. 4 is a View in side elevation of the marker, viewed from theleft ofFig. 2. I

Referring now to the drawing, the numeral 1 indicates the head of themarker which is circular in shape and provided with an upper convex orrounded surface 2, which the nature of the metal employed enables to beburnished to a high-degree of polish. The head 1. is convex on its underside, as indicated at 3 in Fig. 3, and is provided with a centralrectangular keeper 4, cast integral with the head and providing a space5 between itself and the under side of the head through which a flat bar6 of flexible metal may be inserted as indicated by the dotted lines inFig.2. The bar 6 prior to being inserted in the keeper 4 may have one ofits ends bent downward at an angle and slightly curved outwardly to forman anchoring I arm 7, Figs- 2 and 3, and after the other end of the baris inserted beneath keeper 4, as shown by the dotted lines of Fig. 2, itis bent downwardly. in the same manner to form an anchoring arm 8.

Each of the arms 7 and 8 prior to the insertion in the keeper, asdescribed, is cut away at its outer end to form pointed end members 9,Fig. 4, to enable, the arms of the anchoring member to penetrate thematerial of the pavement under the force of blowsadministered to thehead 1'. As stated, each of the arms '7 and 8 is curved outwardly, asindicated at 10 in Fig. 2,. so that whenv driven into the material ofthe pavement these arms will tend to separate, or to pass into thematerial of the pavement on diverging lines, so as to offer a greaterresistance to any force tending to lift the marker from the pavementthan if they weredriven into the pavement in a substantially verticalposition. v

Cast integral with the keeper 4 and projecting of the anchoring device.

Application October 31, 1930. Serial No.'492,501 2 Claims. (01. 94-15)downwardly from the under side thereof is a tapered spike 11 having apointed end l2and which is somewhat longer than the arms 7 and 8 Thespike constitutes the main penetrating member of the marker and may bedriven. by blows on the head directly into the pavement. The spike11,-being centrally located enables the marker to be, accuratelypositioned on the pavement and, when driven home will securely hold theheadagainst any force tending to displace it, or move it laterally. Themetal from which my improved marker is made is a novel malleable ironmetal, which is described and claimed in my pending application SerialNumber 477,185, filed August 20, 1930. It is sufficient for the presentto say that this metal may becast, is rust-proof, acid-proof,non-magnetic and capable of taking a high chromium fin ish or polish, Itmay also be of any required deg gree of hardness. The anchoring memberor bar 6 and the spike 11 are also made from the same metal; and thus,when anchored in the pavement, my device forms a permanent markerunafiected by weather conditions and consequently immune from rust ordisintegration.

' In driving the marker home a suitable bumper, of wood or the like,would be placed on the head of the marker to protect its surface fromthe blows of the sledge hammer driving it into the pavement. Y

Iclaim: 1. A street markercomprising a cast metal head provided on itsunder side with an integral keeper spaced from said underside, a spikecast integral with and projecting at right angles to the under side ofsaid keeper and a flexible anchoring memher mountedin said keeper havingpointedarms projecting downwardly on opposite sides of said spike.

2. A street marker comprising a con-cavojconvex circular head polishedon its convex or upper side, a keeper on and spaced from its under sideand a spike projecting from said keeper, said parts being cast as anintegral structure, and an anchoring member comprising a fiat bar offlex- 1:05 ible me tal having pointed ends, and positioned centrally insaid keeper and bent downwardin the same direction from opposite ends ofthe keeper to project in diverging lines from opposite sides of saidspike. 1
